xlock locks the X server till the user enters their pass- word at the keyboard. While xlock is running, all new server connections are refused. The screen saver is disabled. The mouse cursor is turned off. The screen is blanked and a changing pattern is put on the screen. If a key or a mouse button is pressed then the user is prompted for the password of the user who started xlock. If the correct password is typed, then the screen is unlocked and the X server is restored. When typing the password Control-U and Control-H are active as kill and erase respectively. To return to the locked screen, click in the small icon version of the changing pattern.

libcurl is a client-side URL transfer library, supporting FTP, FTPS, HTTP, HTTPS, SCP, SFTP, TFTP, TELNET, DICT, LDAP, LDAPS and FILE. libcurl supports SSL certificates, HTTP POST, HTTP PUT, FTP uploading, HTTP form based upload, proxies, cookies, user+password authentication (Basic, Digest, NTLM, Negotiate, Kerberos4), file transfer resume, http proxy tunneling and more! This package provides a Haskell binding to libcurl.

Poslib is a portable C++ DNS library, a part of Posadis project. It consists of two parts: a client library and a server library. Using the client library, you can simply develop applications that use the Domain Name System (DNS). It includes many functions for resolving, domain-name manipulation and Resource Record (RR) creation. The server library, based on the client core, can be used to develop DNS servers. By implementing a query entry-point function using the Poslib library of functions, you can easily create DNS servers, without worrying about low-level details such as DNS message compilation, domain-name compression and UDP/TCP transmission.

Every UPnP device and UPnP client (or control point in UPnP terminology) needs to listen to SSDP packets broadcasted to the group 239.255.255.250:1900. When several UPnP devices are running on the same server, or several UPnP control points are trying a discovery process on the same server, there is concurence to open a bind a socket on the UDP port 1900. MiniSSDPd can also provide a history of the SSDP NOTIFY packets sent on the network during a period of a few minutes and it keeps track of all UPnP devices that announced themselves on the network through SSDP NOTIFY packets.

OpenID is a decentralized identity system, but one that's actually decentralized and doesn't entirely crumble if one company turns evil or goes out of business. An OpenID identity is just a URL. You can have multiple identities in the same way you can have multiple URLs. All OpenID does is provide a way to prove that you own a URL (identity). Anybody can run their own site using OpenID, and anybody can be an OpenID server, and they all work with each other without having to register with or pay anybody to "get started". An owner of a URL can pick which OpenID server to use.

'tsshbatch' is a tool to enable you to issue a command to many servers without having to log into each one separately. When writing scripts, this overcomes the 'ssh' limitation of not being able to specify the password on the command line. 'tsshbatch' also understands basic 'sudo' syntax and can be used to access a server, 'sudo' a command, and then exit. 'tsshbatch' thus allows you to write complex, hands-off scripts that issue commands to many servers without the tedium of manual login and 'sudo' promotion. System administrators, especially, will find this helpful when working in large server farms.

ldapvi is tool to update LDAP entries with a text editor. It is: - Written in C; - Reasonably fast and small. The ldapvi client needs about as much time for receiving entries as the OpenLDAP server needs to send them, which should be fast enough; - Shows a summary of changes before committing them. Details of the changes can be previewed in LDIF format; - Uses an LDIF-like format in the editor (which should be easier to use interactively than standard LDIF); - Can rename entries; - Does not give up easily. On error, you can edit the file again, or rebind to the server and try again.

These modules are supposed to be used with the Apache server together with an embedded perl interpreter like mod_perl. They provide support for basic authentication and authorization as well as support for persistent database connections via Perl's Database Independent Interface (DBI). o AuthDBI.pm provides authentication and authorization: - optional shared cache for passwords to minimize database load - configurable cleanup-handler deletes outdated entries from the cache o DBI.pm provides persistent database connections: - connections can be established during server-startup - configurable rollback to ensure data integrity - configurable verification of the connections to avoid time-outs.

The Network Audio System is designed for playing, recording, and manipulating audio data over a network. Like the X Window System, it uses the client/server model to separate applications from the specific drivers that control audio input and output devices.

rebot3.pl renames MP3 files that you have grabbed from audio CDs with the track name, number, album, and/or artist. It does so by using either a remote CDDB server or a local CDDB created by cd (and other) players like xmcd, kscd or xmms. With rebot3.pl you can also add or remove ID3 (version 1) tags to/from the MP3 files.
